A high-speed data communication scheme based on embedded clock is proposed,its error control encoding algorithm and performance analysis are given.Clock information is embedded into high-speed serial data stream by using of channel encoding modulation technology,self-synchronous transmission is achieved and the up-limits of transmission distance and transmission data rate in external synchronous mode are broken through,long-distance transmission bandwidth is up to 3.0Gbps.According to features of high-speed modulated channel,interleaving technology is introduced to classic Hamming code theory,thereby possible continuous error code is converted to single random error,which simplifies the algorithm;and encoding efficiency and error correction performance both get improved.The decoding circuit features less delay,easy for implementation and easy to control code rate,therefore this code scheme can be easily used in high-speed data communication,and transmission reliability under low signal to noise ratio can be improved significantly.
